The properties, structures and blood compatibility by platelet adhesion and deformation of segmented poly(urethaneureas) (SPUU's) with various aliphatic diamine chain extenders were investigated. The SPUU's containing diamines with an odd number of methylene units showed a remarkable degree of phase mixing between the hard and soft segments. I.r. spectra of SPUU's indicated that the state of hydrogen bonding depended on the number of methylene units in the diamine. XPS measurements revealed that the surface concentration of soft segment was independent of diamine structure but the state of microphase separation strongly depended on the number of methylene units in the diamine. The SPUU's with an even number of methylene units in the diamines showed less platelet adhesion and deformation than those with an odd number of methylene units in the diamines.
